Latest ffmpeg yields error for some flv files:
{{{

}}}
Increasing 'analyzeduration' and 'probesize' won't help. Output file has
no video stream.
Older versions (2.6.x) work as expected, so I assume this is regression
bug.
Also I can fix flv file metadata with yamdi, after that everything works
fine:
{{{
yamdi -i bad.flv -o good.flv
}}}
How to reproduce:
{{{
ffmpeg -i bad.flv output.mp4
}}}
